. SPECIFICATION formingpart of Letters Patent No. 381.0615, dated April 10, 1888. n

Application led August 4, 1887. Serial No. 246,129. (No model.)

To all whom, it may concern:

Be itknown that I, COLUMBUS W. DONNELL,

a citizen ofthe United States; residing at Fulton, in the county of Callaway and State of Missouri, have invented certain new and useful Improvements in Bed-Springs; and I do declare the following to be a full, clear, andy exact description of the invention, such as will enable others skilled in the art to which it ap- [0 pertains to make `and use the same, reference being had to the accompanying drawings, and

to the letters and; figures of v reference marked I k2o and mutually bracing each other.

The improvement consistsin having the'upper end of thespring extended and vbent in a series of folds about in the plane of the top of the spring, and havngsaid end bent and brought back beneath the folds midway of 3o tures of construction and combination of parts,

their ends and engaged with the spring by havingits end extended down within the convolutes of said spring.

The improvement consists in the novel fea-l which willbe more fully hereinafter set forth and claimed, and Nshown in the annexeddrawj ings, in whichn i 1 f n Figure 1 is a perspective view of two springs embodying my invention; Fig. 2, a plan View of a bed-bottom composed of springsvconstructed in accordance with Iny invention;

Fig. 3, a sectional view on the line X X of Fig. 2.

4o The spring'ls made of a single wire having one endy formed into a/coil-spring, A, ofdesired pattern, andthe other end bent to form a series of folds, a,about in the 4same plane as the top of the spring. Said end is projected beyond'thefolds and forms the interlocking yloop a and the return or supporting arm a?, extended back beneath thev folds at right angles thereto and midway of their ends. The. inner end ofthe return or,V supporting arm is 5o bent down substantially at right'angles, and

extends within the convolutes of the spring.L The folds a ll the gap between the springs K and are supported bythe return-arm `a. The` lower end of the spring is formed into a clamp f lower convolute of the spring. rlrhesprivng is by having the end e bent to extendfacro'ss the secured in place by clamping the support, bed-vA volute and the bentend e.

Figs. 2 and 3 show a bed-bottom composed .of my improved springs arranged in parallel the bed-slats B and their upper ends inter-` spring embraced byfthe loop a of tliespring next in order. .y Y

V`Having thus described my invention, what'I 'ist 1.The herein shown and described spring formed on one end', and having its other end bent to form a series o f return folds wholly to one side of and aboutin theplane of' the npper convolute of the spring, the interlockingright angles to the return t'oldsv and located p midway of their ends, andthe downward ex- "tension a3 for engaging with the convolutes of posegspecified.

of single springs arranged iny parallel lines of return folds between.' each two springs and at right angles to the line of springs, and having said extended portion of onespring interlocked with the next adjacent spring and brought back beneath its folds to support; them, and having the inner end of said extension bent down and engaged withr the convovlute of the spring, of which it is anintegral partsubstantially as described. p 1

In testimony whereof I afiixkmysignature in presence of two witnesses.
